Thanks for editing this timeline. While the syntax may look complicated, it's really quite simple.

The periods should all be accurate, as they are taken from the 2009 geological timescale, so you are most likely to want to edit the arrowed notes. Scroll down towards the bottom and you'll notice something like:

|note1=Something happened

Just add more notes, incrementing the number each time! If you want more precise control, details are available at {{Graphical timeline}}. Any problems, just contact Verisimilus T.
